Glucagon-like peptide-1 vs Retatrutide
The incretin that anchors the modern metabolic toolkit. An investigational GIP/GLP-1/glucagon triple receptor agonist. Side by side: type, evidence tier, receptor, molecular weight, and half-life — the same fields as each monograph, rearranged so the engineering difference is visible.

Common questions
- What is the difference between Glucagon-like peptide-1 and Retatrutide?
- Glucagon-like peptide-1 is an endogenous hormone; Retatrutide is an engineered analog based on Glucagon-like peptide-1. Glucagon-like peptide-1 signals at GLP-1 receptor (GLP-1R), a class B GPCR; Retatrutide signals at GIP + GLP-1 + glucagon receptors.
- How do the half-lives of GLP-1 and Retatrutide compare?
- The reported circulating half-life of Glucagon-like peptide-1 is ~1–2 min (native; DPP-4 cleaved); Retatrutide is ~6 days. These are reference values for the native or representative form — educational only, not dosing advice.
